I trust Gettleman. Like Newton said these guys know more about football than we likely ever will.

DG believes the line of scrimmage is of the utmost importance, he showed it last April with 3 LOS players in the draft. He'll prove it again this year.

I've become a huge David Newton fan.

it's not rocket science. You witness it in college every week. The biggest difference between mid majors and BCS conferences are the players on the offensive and defensive lines. If you can hold your own in that regard, you will play tight. Witnessed by Appalachian being down only 17-7 to UGA at halftime last season. They also beat Michigan because the offensive line matched up well with the defensive front of Michigan.

If Cam doesn't have time to find his man(in time- Ted Ginn streaking down the sideline on a sack he took late in the game against San Fram comes to mind) then we will be abysmal against teams with solid fronts again.

Below is a very good article regarding tackles.( A must read) from PFF with stats to support.I have also pasted the summary or the article for those of you who hate to read

Final Word

There’s a lot to digest here, but it can be summed up rather quickly. The right tackle should no longer be viewed as the athletic inferior to the left tackle and teams should change their team-building strategy to make this happen. Today’s passing NFL makes it a necessity to have two competent pass protectors on the edge and when scouting players, if a tackle is deemed to not be good enough to play left tackle, well you’re better off just putting him at guard rather than exploiting him at right tackle. There’s no hiding — defensive coordinators will find him.

I think we draft a future LT. 1st round. I also believe that OTA/Mini Camps/Training Camp starts with Bell on the left side. It will be his position to lose. If no one beats him out then Rivera and Gettleman's belief that he will be better on the left side than the right is true. If he loses it don't be surprised if he loses both positions and ends up 2nd string LT.
